An Experimental Evaluation Of Explosives In Blasting Limestone And Granite, Harve Preston Nelson

Doctoral Dissertations

"The purpose of this study was the evaluation of military and commercial explosives. A standardized index of effectiveness was used as the basis of comparison.

Testing was conducted at the Experimental Mine of Missouri School of Mines and Metallurgy at Rolla, Missouri, and at Graniteville, Missouri. At the school mine, 16 drift rounds, 8 slab rounds and 70 quarry tests were made in the dolomitic limestone. This rock, known locally as the Quarry Ledge of the Jefferson City formation, is of Ordovician Age"--Abstract, page ii.

Effects Of Higher Speed Explosives In Drift Rounds, Harve Preston Nelson

Masters Theses

"There is much still to be learned of what takes place in the actual explosive zone of a rock blast. Many factors, both known and unknown, have individual and collective effects. A program is now in progress by the Mining Department of Missouri School of Mines and Metallurgy for developing and preserving information about some of the factors affecting the use of explosives. Some work has been done. More is now being completed by Messrs. R. J. Jones and J. B. H. Fitz-William. Present plans call for continuing the research and gathering data on this subject which is so important …
